HMC441LP3

Overview

The HMC441LP3 is a broadband GaAs PHEMT MMIC medium power amplifier manufactured by Analog Devices Inc. It operates within a frequency range of 6.5 to 13.5 GHz. The device provides a typical gain of 14 dB and delivers a saturated output power of +20 dBm at 20% Power Added Efficiency (PAE). It requires a single 5 V supply voltage with a current consumption of approximately 90 mA to 115 mA. Key performance metrics include a noise figure of 4.5 dB to 4.75 dB, a 1 dB compression point (P1dB) of 17 dBm to 18 dBm, and a third-order intercept point (OIP3) of 29 dBm. The component is housed in a leadless 16-VFQFN surface-mount package measuring 3x3 mm.

Feature Summary

• Utilizes GaAs PHEMT MMIC technology for broadband operation across C-band and Ku-band frequencies
• Integrated medium power amplification stage designed for high efficiency and linearity
• Leadless QFN surface-mount package facilitates compact PCB layout and thermal management

Applications

• Point-to-point microwave radio links
• Satellite communication ground stations
• Electronic warfare systems
• Test and measurement equipment

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as HMC441LP3ETR indicate tape-and-reel packaging while HMC441LP3(E) denotes the standard lead-free plastic QFN form. Confirm RoHS compliance status, noting that some sources specify adherence to ROHS3 standards. Ensure compatibility with the required 5 V supply rail and verify that the 16-QFN footprint matches the target PCB design. Cross-reference the manufacturer part number against distributor catalogs to distinguish between cut tape, reel, and Digi-Reel options based on production volume requirements.

Selection Notes

Select this component for applications requiring moderate output power and wide bandwidth without external matching networks. The integrated design simplifies circuit topology compared to discrete solutions. Consider the thermal dissipation capabilities of the 16-QFN package, which supports up to 760 mW power dissipation. Evaluate the noise figure specifications against system sensitivity requirements, particularly for low-noise front-end stages. The fixed 5 V supply requirement dictates power budget planning for battery-operated or regulated systems.

Part Context

The HMC441LP3 belongs to the HMC441G series of RF amplifiers from Analog Devices Inc. This family focuses on broadband MMIC solutions for wireless infrastructure. The device complements other components in the signal chain by providing gain and power handling in the 6.5–13.5 GHz range. It is distinct from lower-power drivers or higher-power final stages, serving as an intermediate amplification block. The use of GaAs technology ensures robust performance in high-frequency environments typical of modern communication systems.
